'As shown in Figure i of the drawings, the shank 11 of the anchor is locked to the head 10 thereof by one of two locking members 16 having a hooked portion 17 which is in locking engagement with a shoulder 18 formed on the head of the anchor. The locking members 16 are pivotally connected on opposite sides of the shank 11 on a pin 19 extending through the shank and through the members 16. Said locking members preferably are independently movable with respect to each other and each is provided with a weighted portion 20 for holding the hooked portion 17 in a position to hook over and remain in hooked relationship with the shoulder 18 as the shank swings downwardly from a vertical position to the position shown in Figure at, and also for assisting the locking member 16 to move out of locking engagement with the shoulder of the head when the shank 11 is moved toward a vertical position from that shown in Figure YVith the parts as shown in Figure 1, the shank 11 is prevented from moving downwardly relative to the head of the anchor, the weight of the shank and also the weight of the chain 21, or at least a portion thereof, and its clevis member 22 connecting it to the shank 11, act in a manner to cause a relatively quic ripping and hooking action oi the flakes into the bottom of the sea, this being especially true in view of the fact that the weight of the shank l1, clevis 22 and chain 21 act through a relatively long lever arm. it will be understood that the shank 11 may be locked to the other side of the head by the associated curved actuated locking inen'iber 16 in a manner similar to that shown in Figure 4 of the drawings.

Reference being had particularly to Figure 1, it will be noted that the head 10 adjacent the shoulders 18 is provided with recesses 23 and that one wall 24 of each of said recesses is curved or cam shaped to hare a cam-like action on the hooked portion 1'? of the associated locking member 16 for positively lifting the hooked portion 17 out of engagement with the shoulder 18 as the shank 11 is raised from the position shown in Figure 4-. It will be noted that each cam surface 24 extends to a point be yond the outer edge of the associated shoulder 18 for positively insuring a complete unlocking movement of the locking member 16 with respect to the head. The hooked portion 17 of the locking member 16 is permitted to have a riding movement on the associated cam surface 24 by virtue of the clearance between the inner stop wall 13 of the head and the associated side of the shank 11. A further advantage is provided by means of the arrangement shown, in that if the hooked portion 17 should fail to pass down into locking engagement with the shoulder 18 upon a downward movement of the shank, it would be necessary only to raise the shank slightly without lifting the head or the flukes of the anchor preparatory to a second attempt to lock the parts together.

Each locking member 16 is provided with a laterally extending projection 25 adapted to engage the shank 11 for limiting the rela tive movement of one with respect to the other and more particularly to prevent the locking members from turning over or assuming abnormal positions from which they could not automatically be returned for proper functioning.

It is my intention to cover all modifications of the invention falling within the spirit and scope of the following claims.

I claim:

1- A stockless anchor including a head, a shank movably connected thereto, means for locking said head and shank in a given relative position for creating a gripping leverage, causing a quick gripping action 01": the anchor, and means for giving the locking means a positive unlocking movement for unlocking said head and shank.

2. A stockless anchor including a head, a shank movably connected thereto, means for locking said head andshank in a given relative position for creating a gripping leverage, causing a quick gripping action of the anchor, and means for positively unlocking said head and shank.

3. A stockless anchor including a head, a shank movably connected thereto, means for locking said head and shank in a given relative position for creating a gripping leverage, causing a quick gripping action of the anchor, and cam means for positively unlocking said head and shank.

4:. A stockless anchor including a head, a shank movably connected thereto, a pivotally mounted locking member carried by said shank and having a portion adapted to engage the head for locking the shank and head in a given predetermined relative position, and means for positively moving the locking member out of locking engagement for releasing said head and shank.

5. A stockless anchor including a head provided with a locking shoulder and a guide portion associated therewith, a shank movably connected to the head, and a looking member carried by said shank and movable into engagement With said shoulder for locking said head and shank, said locking member being positively'moved out of locking position by said guide portion.

6. A stoekless anchor including a head, a

shank pivotally connected thereto, means for locking said head and shank in a given relative position when the shank has moved from a vertical position a predetermined locked position.
